New fully electric long-range city bus

Summary

Electric-powered city transport vehicles will help cities reduce air pollution and increase energy efficiency, two goals that are in line with European energy plans, which aim to reduce CO2 emissions by 20% for the year 2020.

Designing a 100% electric vehicle that is capable of transporting passengers in city environments involves tackling a variety of technical problems related to managing energy inside the vehicle and increasing the lifespan of the internal energy storage systems (batteries).

The IEB project has led to the design and manufacture of an electric vehicle that has an 76-passenger capacity and is able to complete its entire shift each day off a single overnight charge. This eliminates the need for intermediate charging points and guarantees that service downtimes for these vehicles are similar to the vehicles that are currently in service, all of which will make it easer to introduce these electric vehicles into the market.

Objectives

Design, manufacture and put into service an electric vehicle that has an 76-passenger capacity for city transport.

Guarantee full operational autonomy from a single charge during the period that the vehicle is not in operation.

Develop an efficient power management system that maximizes the vehicle's range and the lifespan of all the energy storage subsystems.

CEIT-IK4's role

Develop the advanced algorithms that manage the energy and power flows within the vehicle. These types of algorithms modify all the vehicle's systems in order to maximize autonomy without requiring driver intervention.

Design and install internal energy storage systems that are able to guarantee a high number of life cycles (consecutive charges and discharges).

Design and develop of power converters (storage system) that are better able to take advantage of the energy stored in the vehicle.
